PTC Heating Element And An Electric Heating Device

Electric heating device for a motor vehicle, comprising:

• a housing defining inlet and outlet openings in which several PTC heating elements are arranged, wherein
• each PTC heating element includes two insulating layers with a metallic coating provided on one side and a PTC element arranged therebetween which is provided on oppositely disposed main side surfaces thereof with a respective metallization which is electrically conductively connected to said coating of one of said insulating layers, wherein the metallization on one of said main side surfaces is assigned only to one potential for energizing said PTC element, and wherein the metallization provided on the other of said main side surfaces is only assigned to the other potential for energizing said PTC element wherein, said insulating layer is glued to said PTC element, and said coating of said insulating layers is in direct electrically conductive contact with said metallization of said PTC element;
• and
• wherein an outer surface facing away from each said PTC element is exposed in said housing as an exposed surface for transferring heat to the medium to be heated or is at least in part in heat-conductive contact with a radiator element against which said medium to be heated flows.
